Coconut milk is often a staple fat source for those following a Paleo diet. From a nutritional perspective, it’s an excellent choice. It’s high in saturated fatty acids and medium-chain triglycerides (MCT), which are both easily burned as fuel by the body. MCTs are particularly beneficial in that they don’t require bile acids for digestion, and they’re directly shunted to the liver via the portal vein.
Coconut milk and fruit can be a great snack for Paleo folks, and coconut milk smoothies make a great Paleo breakfast choice – especially in the summer.
So what could be wrong with coconut milk? Here are three things to consider.
Bisphenol-A
Bisphenol-A (BPA) is a chemical that has been used in consumer goods since the 50s. It’s found in reusable drink containers, DVDs, cell phones, eyeglass lenses, automobile parts and sports equipment. While the research on BPA is still mixed (some studies indicating harm and others not), given the uncertainty I think it makes sense to avoid it whenever possible.
So what’s the solution here? In short, if you want to be on the safe side and reduce your exposure to BPA, you have to reduce your consumption of canned foods (including coconut milk) as much as possible. I made this recommendation in 9 Steps for Perfect Health-#3: Eat Real Food. A study published in Environmental Health Perspectives found that families who ate fresh food for three days with no canned food, and using only glass storage containers, experienced a 60% reduction of BPA in their urine. The reductions were even higher (75%) for those with the highest BPA levels at the beginning of the study.
The good news, however, is that there are brands of coconut milk with BPA-free cans or carton packaging. One is Native Forest, which you can purchase on Amazon if it’s not available at your local store.
Coconut milk can also be made quite easily at home, with coconut flakes, a blender and cheesecloth. Here’s a video to show you how (get a load of the soundtrack). I find that blanching the coconut flakes prior to blending improves the results.
Guar gum
It’s primarily the endosperm of guar beans.
Beans and legumes have a variety of compounds in them that make them difficult to digest, especially for people with digestive problems (1 in 3 Americans, from the latest statistics). In my clinical experience, many patients with gut issues improve when they remove guar gum from their diet—including canned coconut milk.
There’s no evidence that guar gum may cause serious harm. So, if you’re able to tolerate guar gum, there’s no reason to avoid it. If it does give you digestive trouble, look for a brand that’s free from guar gum. The other option, of course, is making coconut milk at home.
Fructose malabsorption
Fructose malabsorption (FM) is a digestive disorder characterized by impaired transport of fructose across the small intestine. This results in increased levels of undigested fructose in the gut, which in turn causes overgrowth of bacteria in the small intestine. Undigested fructose also reduces the absorption of water into the intestine.
Symptoms produced include bloating, gas, pain, constipation or diarrhea, vomiting and fatigue (to name a few). Recent research has also tied fructose malabsorption to depression.
Lest you think this isn’t a common problem, studies have shown that up to 30% of people in Western countries suffer from fructose malabsorption.
Even in healthy people without fructose malabsorption, however, only about 20-25g of fructose can be properly absorbed at one sitting. Glucose assists in transport of fructose across the intestine, so in general foods with equal amounts of glucose and fructose will be better absorbed than foods with excess amounts of fructose (in relation to glucose).
While fructose malabsorption can cause symptoms in anyone, those with Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD) are particularly affected. While the prevalence of FM is the same in healthy populations and those with IBS & IBD, the experience of FM appears to be more intense in the latter group. This is probably due to the increased visceral sensitivity common in IBS and IBD patients.
In fact, one of the most promising clinical approaches to managing IBS & IBD right now is the low-FODMAP diet. FODMAP stands for Fermentable Oligo-, Di- and Mono-saccharides And Polyols. These include:
- fructose (fruits, honey, HFCS)
- fructans (wheat, onions)
- lactose (milk sugar)
- polyols (sugar alcohols like sorbitol, xylitol & mannitol, along with fruits like apples, pears and plums)
- galactooligosaccharides (legumes & beans, brussel sprouts, onions)
- other sweeteners like polydextrose and isomalt
Studies have found that restricting FODMAPs can significantly improve the symptoms associated with IBS, IBD and fructose malabsorption.
What does this have to do with coconut milk, you ask? According to Drs. Gibson & Barrett, experts in fructose malabsorption, coconut milk is a FODMAP and should be avoided by people with digestive conditions like IBS & IBD.
According to NutritionData.com, coconut milk has very little sugar of any kind – including fructose. Nevertheless, I do have patients that cannot even tolerate homemade coconut milk (which has no guar gum in it), even though they are fine with coconut oil. I assume that they are reacting to the fructose in the coconut milk – but I can’t be sure. According to Monash University, small quantities (up to 1/3 of a cup or 80g) of coconut milk may be tolerable for those who are sensitive to FODMAPs.

Recommendations
Let’s bring this together into recommendations for three different groups of people:
- Women who are trying to get pregnant, pregnant or breastfeeding, children and other vulnerable populations (chronically ill): should avoid canned coconut milk products except for those that are BPA-free, like Native Forest and Arroy-D. Note: Native Forest is organic, but Arroy-D is not.
- People with digestive problems (IBS, IBD, GERD, etc.): may want to avoid coconut products entirely, except for coconut oil
- Healthy people: may be fine with canned coconut milk, provided they don’t react to the guar gum, and provided they’re willing to take the side of industry scientists that claim BPA doesn’t cause harm in humans
Want organic coconut milk – but without the BPA and guar gum?
There are available options to buy organic, guar-gum-free coconut milk in a BPA-free container. Or, with a little extra effort, you can easily make this at home yourself.
- Purchase coconut cream (Let’s Do Organic and Artisana are good choices) and blend with water to make coconut milk.
- Purchase shredded coconut (again, Let’s Do Organic is a good choice), and follow the instructions below for making homemade coconut milk.
Homemade coconut milk instructions
Ingredients
- 4 cups water
- 1.5 – 2 cups unsweetened coconut flakes
Instructions
- Heat water until hot (but not boiling).
- Add shredded coconut and water to blender (preferably a Vitamix!
) If all of the water won’t fit, you can add it in two batches.
- Blend on high for several minutes until thick and creamy.
- Pour through a colander to filter out the coconut pulp, then squeeze through a cheese cloth or nut milk bag
to filter the smaller pieces of coconut.
- If you separated the water into two batches, put the strained coconut back into the blender with the second batch of water.
- Drink immediately or store in the fridge. Fresh coconut milk should be used within 3-4 days of making it for the best flavor and texture.

This is what experienced when i was in my teens about 45 years ago. To us in Singapore we will make coconut milk for cooking and making desserts only. We dont drink coconut milk as a “milk” drink. Coconut milk is made by buying grated old (not young green) coconut which is brown in colour after it has gone through the green period. The flesh is very hard by then and it is finely grated. The grated coconut is then mixed with some salt water and pressed out with a muslin cloth. The coconut “milk” is then used in curries, or desserts such as bananas cooked in coconut milk with coconut palm sugar.
Coconut water comes from green young coconuts and at that stage the coconut flesh is soft and can be scraped of the inside of a coconut and served with the coconut water. This is how we used to “drink” iced coconut water with the soft flesh floating in the coconut water.
So coconut water (from young green coconuts) is totally different from coconut milk (from old brown coconuts).
Hope this helps clarify a little more !
Additionally, my grandmother used to make fresh coconut oil by boiling coconut milk until it thickens and separates into the oil and the coconut crunch. The oil is put in bottles for cooking and also as a hair oil (we never used it for skin). The coconut crunch is fried with long beans and is a delicious vegetable dish whenever she made a new batch if coconut oil frim fresh squeezed coconut milk.
Native Forest brand makes a simple coconut milk with no guar and they buy BPA-free cans AND they actually TEST the cans they buy before using them! Available on amazon, but I buy from Thrive Market.

Unfortunately carton boxes also have a plastic lining BPA and all – how else do you think it prevents the coconut milk from soaking the carton?
And yes the best coconut cream is the raw homemade one from dry coconuts using a Green Star or similar juicer.
I think the carton linings are simply food-grade wax.
What about making coconut milk from a fresh coconut? Is that also an option? Would it freeze well?
There is organic Aroy-D Coconut milk. From research I’ve been doing to avoid BPAs, I’ve come across articles stating BPA-free is not necessarily better, because what is often used as an alternative is BPS. This has been shown to be as toxic as BPAs.
